Cherry Times is pleased to publish an excerpt of the reports presented at the International Congress "What biosolutions for quality cherries?" at Macfrut 2024.
Serenade Aso, based on Bacillus subtilis, is the fungicide that Bayer proposes for the control of moniliosis and bacteriosis of cherry and other fruit and vegetable crops.
Serenade Aso has a unique mechanism of action: it prevents fungal and bacterial diseases by acting directly on pathogens. The spores of Serenade Aso compete for space and nutrients, limiting the development of diseases, and interacting with the plant, they induce systemic defense reactions and promote physiology.
Lipopeptides and antibacterial compounds typical of the strain break down the cell wall of fungi and bacteria, causing their death and preventing contamination.
The formulation is based on the quality of the production process for which Bayer boasts unique expertise: during the controlled fermentation phase, Bacillus subtilis QST713 produces a series of natural compounds with specific activities on pathogens and plant defense: Lipopeptides, responsible for the fungicidal action, naturally develop during fermentation and are able to promote plant growth and activate its defenses.
Serenade Aso performs its fungicidal and bactericidal function best when applied in preventive treatments. On cherry and all stone fruit trees, it is applied foliarly at a dose of 4-8 L/ha for a maximum of 6 treatments per year, depending on the disease pressure.
Applications starting from the pre-flowering phase: Serenade Aso helps prevent bacteriosis caused by Xanthomonas sp, with recognized collateral activity against Pseudomonas syringae var syringae.
Applications from flowering to pre-harvest: Serenade Aso helps control monilia attacks in the phases when stone fruits are most susceptible to attack: flowering and pre-harvest. In an integrated defense strategy, applied pre-harvest, Serenade Aso has shown good disease containment, allowing for a reduction in residues on the fruits.
Serenade Aso is permitted in organic farming, and is also the ideal product to be included in integrated pest management programs or with the aim of reducing residues at harvest.

Ovule vitality is the key factor for cherry fruit set. High temperatures during flowering reduce the PEP and compromise fertilization. Targeted strategies like biostimulants and ethylene control can make a crucial difference in warm or high-risk growing areas.

The Chinese market, says Sharon Kirk of Southern Fruits International, has shown more interest in 26mm fruit and 1kg boxes this year. So far there has been very good demand and the fruit will continue to be available for purchase online throughout the season.

Chile’s cherry industry faces a decisive phase: softer exports, heavy dependence on China, more digital consumers and rising technical pressures demand sharper strategies to protect profitability, fruit quality and global leadership in fresh produce markets worldwide.

British Columbia’s Canadian cherry growers expect one of their strongest 2026 harvests in recent years. Larger fruit, higher Brix levels, new varieties and solid export demand strengthen Canada’s position in premium cherry markets across Europe and Asia, too.
